The instructions are quite clear. Alas, when I try to reproduce the steps using my home-build compiler (for which I mean set the `with-compiler` in `cabal.project` to the stage2 compiler obtained by Hadrian), I get:
cabal new-install --lib aeson Distribution/Client/CmdInstall.hs:(361,18)-(363,72): Non-exhaustive patterns in lambda
Interesting, this sounds like a cabal-install bug. What does cabal-install --version say?
Here is the output:
$ cabal --version cabal-install version 3.0.0.0 compiled using version 3.0.0.0 of the Cabal library
Alright, I'm afraid I don't really know what might be going wrong here. Perhaps `cabal new-install --lib lib:aeson` will help? Either way, can you open a cabal-install ticket [1] for this? Cheers, - Ben [1] https://github.com/haskell/cabal/issues
